fhiS invention rolnteS to a cafbureter of tho oonstont lovel type for llSe ith internol oonll)UStion engineS.

The object of the invention iS t0 produce n cheap on(1 SiIn le cofbnreter flioh, be coHSe of itS SInoH oost Hnd effioienoy in obtnining the greatest mnonnt of Ower froin n given anoonnt of aSolene, iS portiCulorly ndaptod for uSo with loWpriCed rood vehicleS Snch aS are nov ooInin on the fI1rket.

X hilo I refef )articnlarly to tho uSo of thiS corbHreter on CyC]o oarS, 1ight fonabouts and the likeitS eHicienoy, CapHoity Hnd perfection of o )orntionin thnt it giveS the lnoSt effeotive Inixtnre of all S )eeds, are sch thot itS 1156 With the heHVier and highpriced nlaohineS ,11ere ooSt iS leSS of an ele Inent, iS I1()t prohibited.

In the mannfaoture of the corbHreterS nov on the Inorket, a lorge part of the ox penSe is inCurred beoauSe of the ooStly n1a Chine Work involved in the fitting of the vHriouS CoverS tHbeS, poSSogeS, volve SeatS, eto., and one of the ohiectS of the preSent in vontion is to prodHCo H Corbureter So oon StrHoted thot thiS Costly ork iS eilIliIloted and the expenSe of Corin the float ohon1ber, the cHrbnreting ohalnber and the voriouS paSSogeS iS largely reduoed. To thiS end, I hove So doSigned the urhHroter that it iS formed of tWo poftS ol integrol memberS hich, inStead of having to be fIlrne(1 X ith XtfeIne exCtneSS So thHt the turned-up edgeS of ono pHrt fit *ithin corerS ondingly turned edgeS of the otheI'.poft, Hre fornled vith tWo Hxto osed plone surfaoeS So that to finiSh the oarbureter after the paftS have been oaSt, it iS only neceSSory to grind theSe pIone or flHt Surfoces by IneanS of o Inoof ino WhiCh iS o weH-knoWn oommefcial afticio inSert o valve Set in )osition in hioh lf iS oonveniently acceSSible, place the )a rf in fegiStration and faSten theln togethr vffh Screws of by other IneanS.

The other featureS of the invention relate to the operation of the oorbureter rathef than to itS deSign vith reference to eaSe of conStruotion and prtiou1r1y to IneonS for oontrolling the ratio of the Tnixture at v vofionS SpeedS. ThiS oonSiStS of a 1 oir float or f1()lt valve in conlbination vith on n right gosolene noZZ]e,

In the preferred forn1 of the invention, the oiI' ffoat iS eighted o1, aS Sh0 n, it iS o weight Serving aS an ai1' Hoat and hoving n o ening to receive the end of the gaSolone noZzle Which iS itself provided With an ont let for the gosolene,.So arfanged thot the poSSage iS opened of olosed, or the opening reduCed of increaSed, ao the float n1oveS uP and do*n.
